## What it is
Relativty is an open-source DIY VR headset project with full hardware, software, and firmware designs, built around an Arduino-compatible IMU and supporting SteamVR. The repository serves as a build guide and driver software for a 3-DoF headset that displays 2K at 120FPS.

## Use cases
- build your own VR headset for cheap
- DIY SteamVR-compatible headset
- learn VR hardware and firmware development
- experiment with IMU-based head tracking
- open-source alternative to commercial VR headsets

## When to choose
- you want a hands-on DIY electronics and 3D-printing project
- you need an affordable open-source VR headset with SteamVR support
- you want to learn or modify VR headset firmware and tracking

## When to avoid
- you want a polished consumer VR product
- you need 6-DoF tracking or knuckle-style controller support
- you are not comfortable with soldering and Arduino programming

## Facets
- artifact type: application
- maturity: active
- function: graphics, simulation, embedded
- domain: hardware, gaming-tools, developer-tools
